Geothermal features manifestation appears in Grao Sakti, Renah Kemumu, Merangin Regency, Jambi Province and their associated of Sumatran Fault Zone and Barisan Range Zone. It is very important to understand the connection both of geothermal manifestation and fault zone of the Dikit Fault Segment (DFS). Geological survey is early study for understanding geothermal features manifestation. It consists of geological mapping, measurement of geothermal manifestation, and the information physical characterized of geothermal features manifestation. Geothermal features of the Grao Sakti is composed of geyser with temperature about 78.5°C - 94.7°C, hot spring with temperature between of 52°C - 62°C, steaming ground, and hydrothermal alteration. The appearance of the geothermal manifestation linkages to DFS and their part of Sumatran Fault Zone. The existence of geothermal features is controlled by DFS which is orientation of Northwest- Southeast and similarly Sumatra Island orientation. DFS’s role as a channel way of reservoir rock geothermal in the direction to the surface geothermal manifestation the formed of outflow zone on the Grao Sakti. DFS is dextral fault system which is narrow graben about 8 - 15 m, composed of hydrothermal alteration of Old Masurai Volcanic Complex dacitic lava and Hulusimpang volcanic breccia. The graben structure is consequence of DFS dextral fault system, where linkage to en-echelon truncation as the result of extensional regime inside DFS system. These is formed of depression zone and their related of pull apart basin. DFS is channel way for the appearance of geothermal features manifestation on the Grao Sakti and its role is significant for geothermal system.
